The US consumes 20 million barrels of oil per day

That's oil consumption, not gasoline consumption. Also typically you can only have 10 to 15% ethanol in normal cars.

Cut out oil not used for gasoline. Now multiply by .1 or .15% and you get how much ethanol we can use as fuel absent other changes. Now 8 billion gallons a year isn't quite a drop in the bucket any more.

The 8 billion gallons is not until 2012. Currently, we produce less than 5 billion gallons. Currently, the US consumes roughly 146 billion gallons of gas per year. Ten to 15% of that total is 14-22 billion gallons. Hence, 5 billion is a drop in the bucket when you consider how little it reduces our dependency on oil.

to make that 4.9 billion gallons of ethanol, it took 1.6 bushels of corn......which is roughly 14% of the annual US corn crop.

That's a lot.

14% is a lot?

Its also going up. And there are a number of proposals to increase it even more.

Yes, and they are talking about using grasses instead of corn because they produce more fuel.

To look at it another way - Assume your data is accurate. Now assume we move 100% of corn production to ethanol. We only get about 35 billion gallons of ethanol per year, still well short of 840 million gallons isn't it?

To sum up -

1 - The portion of corn that goes to ethanol is large and rising.

It isn't large and it may not rise all that much more.

2 - Don't look to ethanol to be more than a marginal part of reducing gasoline and/or oil use.

I don't disagree with you there.

There is third point.......you gave out erroneous data.
